Europe can't outlaw filtering in countries outside europe, obviously, so what would be the point?.

(1) For ourselves!!

(2) It makes it a lot harder for other countries(i.e. the U.S.) to 'fool' their own electorate into accepting practices that would be or going in the direction of being - a lot more draconian, less free in several ways, and more 'nanny state'{that's being polite} than what would be the new norm over the pond in Europe!
